The history of acceptance of new theories frequently shows the following steps: At first the new idea is treated as pure nonsense, not worth looking at. Then comes a time when a multitude of contradictory objections are raised, such as: the new theory is too fancy, or merely a new terminology; it is not fruitful, or simply wrong. Finally a state is reached when everyone seems to claim that he had always followed this theory. This usually marks the last state before general acceptance.

Interpretation

What this quote means

New ideas often face skepticism before gaining acceptance, illustrating the challenging journey of scientific theories. Over time, criticisms fade, and the ideas are embraced as obvious truths.

Kurt Lewin highlights the typical progression of how innovative theories are received in scientific discourse. Initially dismissed as nonsense, these ideas attract criticism and skepticism as they challenge established norms. However, with time, as they gain traction and credibility, the very same theories are eventually embraced and recognized, often with individuals claiming they have always supported them. This cycle emphasizes the sometimes arduous path of acceptance for groundbreaking thoughts and innovations.

More from Kurt Lewin

The American culture ideal of the "self-made-man," of everyone "standing on his own feet" seemed as tragic a picture as the initiative-destroying dependence on a benevolent despot. He felt and perceived clearly that we all need continuous help from each other, and that this type of interdependence is the greatest challenge to maturity of individual and group functioning.

Fortunately I experienced Max Wertheimer's teaching in Berlin and collaborated for over a decade with Wolfgang Köhler. I need not emphasize my debts to these outstanding personalities. The fundamental ideas of Gestalt theory are the foundation of all our investigations in the field of the will, of affection, and of the personality.
